Complex stresses may occur when(a) loads are inclined to principal axe

1.	Complex stresses may occur when(a) loads are inclined to principal axes(b) loads are along principal axes(c) symmetrical section are used(d) small values of shear and bending moment occur at sectionThis question was posed to me during an interview.I want to ask this question from Introduction to Beams topic in chapter Design of Beams of Design of Steel Structures
Answer» Right ANSWER is (a) loads are inclined to principal axes For explanation I WOULD say: Complex stresses may arise when loads are inclined to principal axes, when UNSYMMETRICAL SECTIONS are used or when large values of shear and bending moment OCCUR at section.
